when i make a request ,the memory increased a little.
i just use the first demo from https://readthedocs.org/projects/pecan/downloads/pdf/latest/
firstly i run the server

then i run "curl" command and memory is increased from 35028KB to 35176KB

if i request diffirent url,even though it is a wrong url,the memory increased

sometime the same request will increas memory ,the most time ,same url will not increase memory
